Question 48Electricity & Electronics - QMED

The correct answer is B) a voltage tester with a high input impedance and a voltage rating higher than any expected measured voltages. This is the correct answer because a voltage tester with a high input impedance minimizes the electric shock hazard. A high input impedance limits the current flow through the tester, reducing the risk of electric shock. Additionally, the voltage rating of the tester should be higher than the expected measured voltages to ensure safe operation and prevent damage to the tester. The other options are incorrect because a low input impedance tester (A and C) increases the electric shock hazard, and a tester with a lower voltage rating than the expected measured voltages (A and D) could be damaged or fail to provide accurate readings.
